To all whom it may concern:

Be it known that I, GUSTAV B. SCHNEIDER,

a citizen of the United States of America,

and a resident of Cincinnati, in the county of Hamilton and State of Ohio, have invented a new and useful Improvement in Station-Indicators for Passenger-Cars, of which the following is a specification.

My invention relates to station indicators, which have a mechanism for moving the sign bearing devices, which are automatically and intermittently actuated at each station to exhibit the name thereof.

at objectof my invention is a station indicator in which the time of exposureof the name of each station will keep in accord with the time of the cars reaching that station, irrespective of the number or places of the stops or of the reversals, or of other incidents of the travel of the carp Another object of my invention is to improve and simplify the means for starting and stopping the motion of the mechanlsm.

These and other objects are attained by the means described in the specification and illustrated in the accompanying drawings, in which Figure 1, is a side elevation of the mechanism and a sectional view of the casing of a station indicator embodying my invention.

Fig. 2, is a sectional view taken upon line 22 of Fig. 1.

Fig. 3, is a sectional view taken upon line '3 3 of Fig. 1.

Fig. 4:, 1s a sectional VlGW, taken upon line 4-4 of Fig. 1.

Fig. 5, is a perspective view upon a reduced scale of my station indicator.

Fig. 6, is a plan view of a portion of the trolley wires and the contact devices to be used with my invention.

Fig. 7, is a side elevatlon of the trolley wires and contact points and of a trolleypole and contact device my invention. L

Fig. 8, is a front elevation of the parts shown in Fig. 7 p

Referrin to the accompanying drawings, in the pre 'erred form of my invention the forming a detail of device which bears the names of the stadisplay opening I), in the casing B, to a winding roll 0, beingheld straight in front of the display open ng by means of guide rolls a Roller Cyhas rotation imparted contact plates to it in one direction, by a drive shaft D, which is alternately driven in opposite directions by electric motor E, which alternately receives a current from the contacts 7, 7, which are carried by the trolley pole F. Contacts j, (5, are adapted to engage G, which are carried alongside of the trolley wire F, by means of side wires g, which receive current from the main wire F, by means of feed wires 9 which are located at intervals along the trolley wire. Contact plates G, alternate with contact plates G at successivestations. Plates G, G, are made angu lar in cross section, and contacts F, F, are each provided with two contacts, which are located upon the legs of the angle plate, in order to prevent the trolley wire, if it becomes broken, from sending a current to the motor.

. Wire f conveys current from contact 7, to the opposite side of the motor from the wire 7, which conveys current from the directions by means of the pinions e, (Z,

which are secured upon the shaft 6 of the motor and the drive shaft D, respectively.

The rotation of the driving shaft in opposite directions is a factor in securing a single movement only of the indicator at each station irrespective of the length or of the number of the engagements of the contacts with each plate.

The means by which the opposite rotations of the drive shaft D are transmitted into a forward rotation of the paper roll, and the means for limiting the rotation of the paper roll, will now be described.

Shaft D, carries at its inner end a pinion oVwhich meshes with a gear wheel H, which is loosely mounted upon a shaft 71. Upon each side of gear wheel H, ratchet wheels 70, 70 are loosely mounted upon the shaft h, the teeth of ratchet wheels 7a, In point in opposite directions. Gear wheel H, carries dogs h, 7f, the former of which. engagesthe teeth of ratchet 7c, and the latter of which engages the ratchet wheel k, so that the rotation of gear wheel H in one direction, rotates ratchet wheel 71:, while leaving ratchet Wheel it" stationary, and the" 7050f which is secured-to theratchet wheel a links.

rotation of gear wheel H, in the opposlte direction, rotates ratchet wheel 7: in that direction and ElQZLVGS irat'chet wheel is stationary. r

The rotations of ratchet-wheels 7c, 'ls are alternately conveyed to paper roll C, by'the following means Mounted upon shaft i ar.e two sleeves M and N, sleeve M has splined upon it one member m, of a clutch, the other member Sleeve N has splined uponit one member n ,'.0f a clutch, the other memberk of which is secured to the ratchet wheel 170. Members m .and a of the clutches are .engagedby' links P and R, the upperendsof which are PiVOtedltO ,a stationaryv plate 1;}, and the lower ends of which are connected The meansof throwing one clutchinas the other clutch is thrown .out of engagement, is as follows:

fRatchet wheels It, is, carry cams K, K, Whichare' stationed. in the path of cams p and '1', .whichare secured upon-the, links P and R, r espectively, .sothat whenuthe cam 1 contacts with cam Kit. carries member at of the clutch away from itsccbperating member, and through the medium of the link S carries member m, of .,the. o pposite clutchinto-engagement with its cooperating vmember. Cams 22,4", are positioned so that one clutch is thrown out before theoflmr is thrown into gear. After passing the contact plate at a station, sinceltheaction of the cam puts the indicator in position .to be actuated only bya contact plate which is positioned upon the ,opposite 7 side of the V the indicator.

'Sleeve'Mhas secured upon it a gear .vvheel m" which engages a pinion 0 upon the shaft 0 ofthe paper roll C. ,Sleeve N has secured upon it ,a-gea-r wheel a, which meshes withQan intermediate gear .T, which is s cur dupon a st d s ftit upon which i se u ed a g a 71. .6 Wh ch-m ith a gear it in/1.0 uponth ishe Inswi ngthnoper onl il .snpposc that. hecar ha passed. the s tion. t i hic is located a contact 1 plate G, i and that ;this

When the contact f strikes :the contact plate '9, current will be imparted to the motor G to rotate it in an opposite direction to that in which it has just been rotated. This will likewise convey an opposite rotation to drive shaft D, which .wilhthrough thepinion d gear wheel H,

and dog 72?, convey rotation to the ratchet wheel which willconvcyrotation to the paper roll shaft 0., by meansof clutch a,

.sleeve N and gear wheels T, T and a. .One vrotationof the ratchet 7c carrles cam K into contact withcam nandgthrows link R into ,a position which opens the .clutch a and closes the clutch m, thereby checking the .Webof paper is advanced at each station a sufiiciehtdistance to exhibit at the display opening the name of the successive station. Having described my invention, what I claim is 1. In astation indicator the combination of a s gn, bearing devlce, an actuator for the sign bearing device, a drive shaft, means for imparting rotation in opposite directions at successive statio 1 1s to. the drive shaft and means forgtransmltt ng motionln a forward d1rect1on. t o: the actuator from the successive rotations of the drive shaft.

2.
